“Subscribe to me” och länken som den nya copyrighten

Here’s what I’m offering:
1) You, the subscriber, agree to give me $9.50 a month for a year, to support my art. This is a donation that supports my work, not the purchase of a particular piece of art.
2) At the end of that year, I’ll put up a webpage with a selection of digital prints (at least 6 pieces, maybe a lot more). You can choose any two prints. There are no additional costs, not even shipping. Effectively, two prints cost you less than half what you would normally pay for one ($125+shipping). That’s your reward for investing in me.
